Abstract: Grafted rubber production including a step for isolating the product from an aqueous phase involves either (a) using an alkali(ne) earth formate as a precipitation agent; or (b) first isolating the product and then working it up with at least one of the working up steps being effected in presence of an alkali(ne) earth formate.

Abstract: The present invention relates to thermoplastic molding compositions comprising a mixture of (A) from 30 to 69% by weight, based on the sum of components (A), (B) and (C), of a methyl methacrylate polymer, (B) from 30 to 69% by weight, based on the sum of components (A), (B) and (C), of a copolymer obtainable by polymerizing a styrenic monomer and a vinyl cyanide, and (C) from 1 to 40% by weight, based on the sum of components (A), (B) and (C), of a graft copolymer obtainable from (C1) from 60 to 90% by weight, based on (C), of a core obtainable by polymerizing a 1,3-diene and a styrenic monomer, (C2) from 5 to 20% by weight, based on (C), of a first graft shell, and (C3) from 5 to 20% by weight, based on (C), of a second graft shell composed of an alkyl (meth)acrylate polymer, with the proviso that the ratio of (C2) to (C3) is in the range from 2:1 to 1:2.

Abstract: The foam has the following properties. Density 5-1000 kg/m 3>, mean pore diameter 1mu m - 1 mm, a BET surface area of 0.1-50 m 2>/g and sound absorption exceeding 50% at a frequency of 2000 Hz at a layer thickness of 50 mm. It contains 1-4000 ppm, related to the weight of the unmodified open cell foam, of fixed particles (b) with a mean diameter (numerical mean) of 5 nm to 900 nm. An independent claim is included for the method of manufacturing the corresponding foam.

Abstract: A process for preparing a supported catalyst comprises the steps of (1) preparation of a copolymer having comonomer units which comprise leaving groups; (2) polymer-analogous reaction with a substituted or unsubstituted cyclopentadienyl compound, and (3) reaction of the copolymer of (2) with a mono-Cp-metallocene compound.
